Claims.

This invention relates particularly to window regulators for use inFisher No Draft ventilating windows. The Fisher No Draft ventilatingsystem is described and, claimed in the Fisher Patent No. 2,048,605. Inthese ventilatingsystems, it is customary to use either a fixed divisionpillar which remains in position regardless of the position of thepanels, or else to use a stile or channel on the sliding panel whichslides up and down with the sliding panel. In the Fisher patent,

an H channel is disclosed and the division line between the two panelsinclines rearwardly from bottom to top. Hence, when the sliding panel isfirst lowered, the stile withdraws from engagement with the frontswinging panel. This arrangement is shown and claimed in the SimpsonPatent No. 2,087,821. Another arrangement which is quite extensivelyused utilizes a vertical stile on the sliding panel but of H crosssection. When the sliding panel is lowered, the weatherstrip on thestile rubs the edge of the swinging panel all the way down and is opento the objection that it wears the strip and also, in a measure,interferes with the lowering operation.

'It is the purpose of the invention about to be described to overcomethese diificulties and yet utilize a vertically disposed stile. This isaccomplished by an arrangement whereby the regulator at the beginning ofthe lowering operation causes the sliding panel to move a slightdistance to the rear to separate the two panels and then the regulatoroperates to lower the sliding panel.

In the drawings:

Fig. 1 is an elevation of the window regulator in connection withfragmentary parts of the two panels showing the panels in their fullyclosed position.

Fig. 2 is a similar view showing the panels after they have beenseparated by ahorizontal movement of the sliding panel.

Figs. 3 and 4 are sections on the corresponding section lines of Fig. 1.

Figs. 5, 6 and 7 are sections taken on the corresponding section linesof Fig. 2.

Fig. 8 is a section taken on the line 3--8 of Fig. 1.

Fig. 9 is a section taken on the section line 9-5 of Fig. 2.

Figs. 10 and 11 are details showing the two positions of the major andminor sectors.

I designates the swinging panel of the Fisher No Draft ventilator, 2 thesliding panel. However, this sliding panel is capable of a smallhorizontal movement as well as a vertical movement.

This movement can be observed by comparing the position of the twopanels in Figs. 1 and 2.

The window regulator comprises a sector type of regulator of a commontype. This includes a clutch, not shown, but contained in clutch case 3,a driving pinion which has teeth that mesh with the usual toothed sector5.

This sector has the usual lifting arm 6. This lifting arm is preferablyprovided with an additional arm 1, the lower end of which travels in thehorizontal guide 8 and the upper end has a roll that travels in thehorizontal guideway 9 on the bottom of the sliding sash 2. This is animprovement described and claimed in Graf Patent No. 2,010,075.

The sliding panel 2 is provided with an H section channel N). This is avertically disposed channel and, when the panels are closed, thischannel straddles the rear edge of the swinging panel and locks the twotogether so as to make a near air-tight seal and, at the same time,prevents one prying the swinging panel open to get into the car from theoutside.

My improvement consists of an arrangement whereby the sliding panel inthe initial lowering operation moves first rearwardly from the posi tionshown in Fig. l to the position shown in. Fig. 2. This is accomplishedby a slight relative movement between the minor sector H and the majortoothed sector 5.

Referring to Figs. 10 and 11, it will be seen in Fig. 10 that a tooth iion the minor sectoris engaged between two teeth on the driving pinion 4.When the driving pinion is turned clockwise, the minor sector It willmove a short distance counterclockwise until the lip IS on the minorsector moves from the position shown in Fig. 10 to that shown in Fig.11. In this latter position, the lip strikes the edge M of the majorsector 5. The pin l5 on the minor sector engages in a notch it in thearm ll. This arm I! has a hooked end it provided with a notch it thatengages the pin 2Q on the bracket 29 attached to the bottom of thesliding panel. When the driving pinion is first turned counter-clockwisein Fig. 1, it first rotates the minor segment ll clockwise. The pin 55,engaging in notch GEE, pushes arm H to the right and arm ll, with itsnotch 59 engaging over pin 28, pushes the sliding window rearwardly fromthe position shown in Fig. l to the position shown in Fig. 2, therebyseparating the two panels a slight distance. This distance is shown bycomparing Figs. 1 and 2 and Figs. 8 and 9.

The sliding arm ll has slots 22 and 23 through which pins 24 and 25,attached to the window regulator plate 26, engage so as to guide the armin its sliding movement. When the pin l5 has passed from the positionshown in Fig. 1 to that shown in Fig. 2, it reaches the mouth of theslot l6 and the flared opening 2'! of the slot now permits the pin toclear the arm I! as it moves upwardly in an arc whose center is thepivot point 28 of the major sector 5 after the two sectors come togetherand move as a unit when the lip 13 engages the edge 14 of the majorsector. The two sectors are held together on the fulcrum pin 29. Atorsion spring 30 biases the minor sector and tends to bring the lip H3in contact with the edge M of the major sector.

In order to hold the major segment in a determined position when thesliding panel is in its uppermost position, a latch 3! spring-pressed byspring 32 and pivoted on the window regulator plate is provided. OnFigs. 1 and 2, the latch is seen contacting with the upper edge of themajor sector 5. As the small sector H makes its limited relativemovement with respect to the large sector, the struck out cam lip 33cams this latch out of the way as will be seen by comparing Figs. 4 and5. The major sector 5 is now free to move past the latch. This latchserves to hold the major sector in a definite position so that, at agiven point in the lifting or descent, the relative movement can takeplace between the two sectors. This cam lip 33 engages in a notch 34 inthe major sector 5 so that, when the two sectors start to move together(as shown in Fig. 5), the cam lip 33 has cammed the latch 3| out ofposition so that the upper edge M of the major sector may now pass thelatch 3|. On return movement, as soon as the upper edge of the largesector passes the latch, the latch drops behind this edge, as shown inFig. 4.

It is not broadly new to provide a window regulator in connection withthe Fisher No Draft ventilating system which will first separate thepanels by a movement of the sliding panel horizontally and then movingthe sliding panel downwardly. A regulator of this type is shown andbroadly claimed in the Kegler Patent No. 2,152,-

055. Nor is the use of my regulator necessarily confined to aventilating system, such as the Fisher No Draft for the regulator per seis useful wherever a window panel has to first move horizontally andthen downwardly and viceversa.
